美国冻结资金,在2025年阻止了一次重大的非洲艾滋病毒疫苗试验,扰乱了多年的研究。 A U.S. funding freeze halted a major African HIV vaccine trial in 2025, disrupting years of research.

2025年,美国的一项行政命令冻结了外国援助,切断了美援署4 500万美元的资金,此后,整个非洲的大规模艾滋病毒疫苗试验停止了。 A major HIV vaccine trial across Africa was halted in 2025 after a U.S. executive order froze foreign aid, cutting off $45 million in USAID funding. 这次试验旨在开发一种适合非洲各种艾滋病毒菌株的疫苗,经过多年的研究和在桑给巴尔举行的一次重要规划会议后,试验已接近启动。 The trial, aimed at developing a vaccine tailored to diverse African HIV strains, had been nearing launch following years of research and a key planning meeting in Zanzibar. 包括Penny Moore和Linda-Gail Bekker在内的科学家们因突然停飞而大受打击,这破坏了以南非妇女数十年数据为基础的进展。 Scientists, including Penny Moore and Linda-Gail Bekker, were devastated by the sudden stoppage, which disrupted progress built on decades of data from South African women. 尽管受到挫折,但研究人员仍然充满希望,他们列举了在了解艾滋病毒行为方面取得的进步,以及目前通过国际合作和替代资金重组试验的努力。 Despite the setback, researchers remain hopeful, citing advances in understanding HIV’s behavior and ongoing efforts to restructure the trial with international collaboration and alternative funding.
